Application Of Pheasant Census Methods In Cache County, Utah, Gordon L. Zorb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An inventory of the stock on hand is a basic step in management. This is true whether the field be business, land, or wildlife management. It is a marginal business man who ignores the basic step of inventory. In the history of wildlife management, however, it has not been unusual to find the cart before the horse. This is not to say that the wildlife manager is, or has been, marginal. His business was inherited ready-made, but often in a bankrupt condition. The problems were there, but not the background of records, techniques, or methodology to cope with them. Often …

Reactions Of The Rocky Mountain Muskrat Ondtra Zibethica Osoyoosensis (Lord) To Drought Conditions At Ogden Bay Bird Refuge, Utah, Edward V. Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perhaps no mammal on the North American Continent has received more attention in the literature than the muskrat (Ondatra spp.), but little of this material pertains to the reactions of muskrat populations to drought conditions. The author was unable to find any literature containing information on the reactions of the Rocky Mountain muskrat Ondatra zibethica osoyoosensis (Lord) to drought conditions in Utah. This information is of vital importance in formulating muskrat management programs in the State.

On many farms the muskrat population represents the greatest cash value of any kind of wildlife, and they utilize swamp areas and marshlands …

The Food Of Pond Fish In Northern Utah, Robert L. Eberhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of ponds in northern Utah supplied mainly by artesian water was poisoned with rotenone during 1949-50. Four hundred and seventy-three fish were obtained for a food habits study, and of these fish, 423, or 89 percent, had food in their stomachs. The species studied were largemouth bass, green sunfish, common bluegill, and black bullhead. Largemouth bass had the widest variety of diet throughout the year but also had the highest percentage of empty stomachs. Green sunfish and black bullhead had the least diverse food habits. Twenty-nine different food items were recorded; those used most commonly were green sunfish, …

Inheritance Of 16 Barley Characters And Their Linkage Relationships, Tejpal Singh Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The assignment of genetic factors to definite loci in the hereditary mechanism has been a great step in the progress of biology. Of the cereal crops, barley (Hordeum sp.), a crop of economic importance, offers a superior opportunity for genetic studies. Its adaptation to wide varieties of conditions, with a wealth of easily differentiated characters and only seven pairs of chromosomes, the barley plant provides excellent material for linkage studies.

Although there is a vast amount of literature dealing with inheritance in barley, yet knowledge of the subject is still very limited. The mode of inheritance of about one hundred …

The Yield And Thiamine, Riboflavin, And Niacin Content Of Alfalfa Hay As Related To Fertilizer Treatment Of Soil, Rasik L. Pathak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa has long been recognised as an outstanding hay plant in terms of both yield and feeding value. It is high in digestible proteins minerals, and vitamins. Because of its long life. it can be economlcally produced. It is of exceptlonal value in maintalning soil fertility by helping to control erosion, by improving the physical condition of the soil, and by accumulating large amounts of nitrogen.

An Annotated Bibliography Of North American Upper Cretaceous Corals, 1785-1950, Bob F. Perkins

Fondren Science Series

Although more than one hundred species of corals have been described from the Upper Cretaceous formations of North America, there has been no attempt, to date, to compile a bibliographic index of the species. The author feels that such an index would be useful to paleontologists in future identifications. The following bibliography includes a list, with annotations, of all available literature on North American corals of Upper Cretaceous age; a catalogue of genera and species; and a plate showing the distribution of species.

The Desert Shall Blossom As The Rose, D. Wynne Thorne

Faculty Honor Lectures

IRRIGATION AGRICULTURE has not received attention commensurate with its significance in either ancient or modem times. Although most ancient civilizations depended on irrigation for their very existence, one can consult volume after volume of history only to find irrigation scarcely mentioned. To the agricultural specialist the great challenge and the strength and weakness of irrigation agriculture is not in constructing Boulder Dams nor in planning winding canals and syphons to carry water from the Columbia River to California. The critical point is on the farms where water is applied to the soil and crops are harvested. There the real battles …

How To Control Insects Harmful To Alfalfa Seed Production In South Dakota [Revised], H.C. Severin

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

In order that a grower of alfalfa seed may have the best chance of producing a. good seed yield, the harmful insects in the alfalfa field must be destroyed, while the beneficial pollinating insects should not be reduced but encouraged. The most harmful insects that affect the seed yield of alfalfa in South Dakota are the following: Grasshoppers of several species Crickets of several species Lygus and other plant bugs Clover, potato and other leaf hoppers Flea beetles of several species

Hindeastraea Discoidea White From The Eagle Ford Shale, Dallas County, Texas, Bob F. Perkins

Fondren Science Series

In 1888 Charles White made Hindeastraea discoidea the type of a new genus of Cretaceous coral. The type specimen was reported to have been collected from the Ripley (Navarro) formation near Terrell, Kaufman County, Texas. The next year Robert T. Hill reported what he considered to be the same species in the shales at Eagle Ford, Dallas County, Texas. The note was not accompanied by a description, and the corals were referred incorrectly to the genus lsastrea. Although the occurrence of these corals in the Eagle Ford has been known to many collectors other than Hill, there has been no …

The Striped Water Snake, Natrix Rigida (Say), In Texas, Lawrence Curtis, Donald Tinkle

Field and Laboratory

Stejneger and Barbour (1943) give the range of the striped water snake as "New Kent County, Virginia and South Carolina to Western Louisiana, excluding peninsular Florida." It was first recorded from Texas four years ago when Brown (1947) listed specimens from Leon (6 mi. nw. of Normangee), Jasper (12 mi. w. of Jasper), Henderson (7 mi. e. of Athens), and Hardin (4 mi. w. of Silsbee) counties. Later Brown (1950) noted specimens from Jefferson (2 mi. n. of Sabine Pass), Liberty (Daisetta), San Augustine (no specific locality), and Tyler (near Warren) counties.
